1. visit ntp.org and find/choose an ntp server that is near you.
2. edit /etc/ntp.conf
and add the server
3. restart the ntp /etc/init.d/ntp.sh restart
( or reboot your MyBook)
From now on, when the mybook boots up, it will go to the internet (assuming it's online)
and synch its time with that of the ntp server.
